(herein called "Arcoms"), Enerdyne Technologies, Inc., a California corporation ("Enerdyne"; Arcoms and Enerdyne are collectively referred to herein as "Borrower"), Housatonic Micro Fund SBIC, L.P., Housatonic Micro Fund, L.P and Lexington Funding LLC (collectively, the "Lender"), as the assignee of First National Bank, a national banking association ("Bank"). RECITALS A. Borrower and Bank entered into that certain Loan Agreement, dated as of December 29, 1998, (as the same has been and may from time to time be modified, amended, supplemented, restated or superseded, the "Loan Agreement"), pursuant to which Bank agreed to extend and make loans ("Loans") available to Borrower upon the terms and conditions contained therein. The Loans are evidenced by (i) the Loan Agreement, (ii) that certain Promissory Note dated December 29, 1998, in the original principal amount of $750,000 (as such amount has been subsequently increased and decreased from time to time (the "Note"), the terms of which were amended by a letter to Borrower from Bank dated February 20, 2001 and those various Change in Terms Agreements, dated February 4, 2000, February 28, 2000, March 13, 2001, May 18, 2001, August 3, 2001, November 5, 2001, and December 20, 2001, (iii) that certain Loan Modification Agreement, dated May 29, 2002 between Bank and Borrower, and (iv) all security agreements, pledge agreements, guarantees, financing statements, subordination agreements and other documents or instruments entered into in connection with the Loans (all of which, together with the Loan Agreement and the Note, shall be referred to herein as the "Loan Documents"). As of the date of this Agreement, the aggregate principal balance of the Loans is $1,500,000 and such principal balance, along with accrued interest thereon, and other charges, costs and expenses with respect to the Loans remains unpaid. Unless otherwise defined herein, all capitalized terms used herein shall have the meanings given to such terms in the Loan Agreement. B. Bank and Lender entered into that certain Purchase and Sale Agreement ("Purchase Agreement"), dated as of September 20, 2002, pursuant to which Bank irrevocably sold, transferred, assigned, granted, and conveyed Bank's right, title, and interest in, to and under the Loans, the Loan Documents and the other Transferred Rights (as defined in the Purchase Agreement) to Lender. C. Borrower is presently in violation of the following covenants set forth in the Loan Agreement: (i) Overadvance default, due to the Eligible Account Deficiency as disclosed in the Borrowing Base Certificate dated July 31, 2002 and failure to submit Borrowing Base Certificates for each calendar month thereafter, (ii) failure to deposit Additional Collateral upon the existence of an Eligible Account Deficiency, (iii) Payment default, as monthly interest payments have not been made since August, 2002, (iv) failure to not allow any Account Payable to a Key Vendor to remain outstanding for a period in excess of sixty (60) days from its due date, and (v) failure to direct all of its Account Debtors to send all future payments on their Accounts Payables directly to Lender, each of which violation constitutes an Event of Default under the Loan Agreement (collectively, the "Current Events of Default"). D. The continuance of the Current Events of Default entitles Lender to, among other things, declare all existing Indebtedness to be immediately due and payable and commence immediate enforcement and collection actions and to exercise such other rights or remedies as are available at law or in equity including, without limitation, remedies available under Article 9 of California's Uniform Commercial Code (collectively, the "Enforcement Actions"). E. Borrower has requested Lender to provide additional loans to Borrower for the purpose of meeting certain of its working capital requirements, and Lender is willing, subject to the terms and conditions set forth herein, to make such additional loans on the terms and conditions set forth herein and in reliance of the representations and warranties set forth herein and the documents to be executed in connection herewith. AGREEMENT NOW, THEREFORE, in consideration of the foregoing recitals and the mutual covenants herein set forth and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound, and to induce Lender to enter into this Agreement, Borrower and Lender hereby agree as follows: SECTION 1. LENDER, ASSIGNEE OF BANK. Borrower hereby acknowledges and consents to the assignment of all rights, title and interest in, to and under the Loans, the Loan Documents and the other Transferred Rights by Bank to Lender and expressly agrees that each Loan Document is hereby amended so that all references to Bank therein shall be references to Lender, as assignee of Bank.

A default in repayment of the Expansion Loans or any other term and condition set forth in the Loan Documents as modified by this Agreement shall constitute an Event of Default under the Loan Documents and Lender shall have the right to accelerate the Loans, including the Expansion Loans, and exercise all other remedies under the Loan Documents; provided, however, that the Current Events of Default shall not trigger Lender's rights to accelerate the Expansion Loans or enforce any other remedies set forth in the Loan Documents relating to the Expansion Loans. 2.3 Expansion Loans shall be made in minimum increments of $100,000 and the proceeds of the Expansion Loans shall be used only for the purpose of financing Arcom's working capital needs.

Additionally, prior to Lender's obligation to make any Expansion Loans available to Borrower, Lender shall have received a re-affirmation of guaranty from each guarantor of the Loans, including such Expansion Loan, and shall have received such other documents as Lender may request and deem necessary or appropriate in its sole and absolute discretion. 2.5 Notwithstanding anything to the contrary in the Loan Documents, from and after the date of this Agreement, the Loans, including the Expansion Loans, shall bear interest, on the outstanding daily balance thereof, at a rate of interest equal to Prime Rate (as defined below) plus 1.5% per annum, calculated on the basis of a 360-day year, subject to a minimum interest rate of 8.0% per annum and a maximum interest rate per annum equal to the maximum interest rate per annum allowed under applicable laws. Notwithstanding anything to the contrary in the Loan Documents, interest on the outstanding Loans, including Expansion Loans, shall be due and payable on the first day of each calendar quarter and, at Arcom's option, either in cash or by adding the accrued interest to the outstanding principal amount of Loans, including the Expansion Loans, outstanding under the Loan Documents. Any interest not paid in cash when due shall be compounded by becoming a part of the Loans, and such interest shall thereafter accrue interest at the rate then applicable hereunder. "Prime Rate" means, on any date of determination, the prime rate as published by the western edition of the Wall Street Journal on the last business day of the calendar month immediately preceding such date. 2.6 Notwithstanding anything to the contrary in the Loan Documents, Borrower promises to pay to Lender the aggregate unpaid principal amount of the Loans, including the Expansion Loans, together with accrued and unpaid interest on the unpaid principal thereof, at interest rates in accordance with Section 2.5 of this Agreement, on or prior to June 30, 2004 (the "Maturity Date"). Notwithstanding anything to the contrary in the Loan Documents, the Loans, including Expansion Loans, may be prepaid in whole or from time to time in part in minimum increments of $100,000 without premium or penalty, along with accrued and unpaid interest on the amount so prepaid. Notwithstanding anything to the contrary in the Loan Documents, any Loans, including Expansion Loans, once prepaid, may not be re-borrowed. 2.7 Notwithstanding anything to the contrary in the Loan Documents, Borrower may sell assets for fair market value (as reasonably determined by the Board of Directors of Arcoms, or a committee thereof) cash consideration with the prior written consent of the Lender (not be unreasonably withheld), provided that the net proceeds generated from sale of any assets of Arcoms shall be applied as follows: ITEM NO.

Notwithstanding such provisions, this release shall constitute a full release in accordance with its terms. Each of Arcoms and Enerdyne hereby knowingly and voluntarily waives the provisions of Section 1542, as well as any other statute, law or rule of similar effect. 10.4 Each of Lender and Borrower agrees that, notwithstanding anything to the contrary contained in this Agreement, Borrower reserves and does not release any of the Releasees from any and all actions, causes of action, suits, rights, remedies defenses, debts, liabilities, obligations, controversies, judgments, executions, claims, costs and demands both at law and in equity which they have or may have against the Releasees, or any of them, whether asserted or unasserted, as to the amount of principal which Lender is entitled to be repaid by Borrower or any guarantor with respect to the Loans and the Subordinated Notes arising directly or indirectly from the purchase of the Loans and Subordinated Notes at a discount; provided, however, that notwithstanding anything to the contrary in the foregoing, each of Lender and Borrower agrees that no inference is intended to be drawn as to the validity of any such actions, causes of action, suits, rights, remedies defenses, debts, liabilities, obligations, controversies, judgments, executions, claims, costs and demands and the foregoing shall not be deemed to be an admission by Lender of the validity thereof.
